Cause of Lapindo Hut Mud Flood Case
Civics Individual Paper OVERCOMING PT.LAPINDO BRANTAS HOT MUD CASE
By: Aditya Rahman Sulaiman 10/HK/295884/19279 International Undergraduate Programme Lapindo hot mud flood case or we usually called it “banjir lumpur panas Lapindo” is an event of the unstoppable mud gush in Kecamatan Porong, Kabupaten Sidoarjo, Jawa Timur and this accident have been happened since 29 may 2006. There are 2 views of the cause of this Lapindo hut mud flood case. First, some scholars said that the primary cause of this event was because drilling mistakes and technical problems. Other theory said that it was happened because natural disaster, this theory explaining that sooner or later hot mud gush will be arise, the lapindo’s mining activity is only the trigger.
First theory believes that there is an eror in the mining activity, PT.LAPINDO is suspected not doing a proper procedure in using the correct brace and bit (mata bor), they use it within different depth which has different thickness and causing a fault. In the begininning, PT LAPINDO won a drilling well tender called “pengeboran sumur Banjar Panji-1” from PT Medici Citra Nusantara as worth as US$24 million. PT LAPINDO was planning to drill the well until 8500 feet or 2590 meter depth. In order to reach that depth, infiltrate the Kujung layer (lapisan batu gamping), anticipate circulation loss potency (losing mud from the formation cause a high density liquid or mud come up) and kick potency (infiltration of other fluide to the upper layer), normally PT LAPINDO is needed to use a casing for its brace and bit. Running their work, PT LAPINDO has already used 30 inch casing for 150 feet depth, 20 inch casing for 1195 feet, 16 inch casing for 2385 feet and casing 13-3/8 inch for 3580 feet until 9297 feet, they only not yet put the last casing, the 9-5/8 inch casing for reach the Kujung layer in 8500 feet. The fact is, PT LAPINDO has a wrong prognosis a drilling term which briefly means drilling method of
